Support Foulborn Choir of the Storm and Skin of the Loyal/Lords

[Mef1729]

Description of the problem being solved:

Mana increased by 50% of overcapped lightning resistance is not supported
50% increased elemental and chaos resistances are not supported

Steps taken to verify a working solution:

• imported the build
• checked resistances and mana against in-game values
• ran tests via docker-compose

This does not work - it does not factor in a number of things (e.g. Purity skills) as a consequence of moving the calculation of resistances that early.

I do have a fix that I can use locally, but it is an ugly hack that conditionally repeats doActorLifeMana and doActorLifeManaReservation. Foulborn Skin support works on its own, but it's a simple one-liner.
